Relative mRNA expression levels of CSE, CBS, and 3-MST in the NG (a, n = 5 duplicates/group) and NTS (b, n = 5 duplicates/group) from Ctrl and RVH rats were measured by PCR. (c, d) The representative bands and expression levels of the CSE (CTH) protein in NG (n = 5 duplicates/group) and NTS (n = 5 duplicates/group) from Ctrl and RVH rats were measured by Western blot analysis, and the data are presented as fold change values normalized to control values. The results were analyzed using two-tailed unpaired Student’s t-test, and averaged data are expressed as the mean ± SD, *P < 0.05 vs. the Ctrl group.
